A Little KenKen History:

KenKen was developed in 2004 by acclaimed Japanese mathematics educator Tetsuya Miyamoto (no, not two guys named Ken). His goal was to improve his students’ math and logic skills... and what better tool than a puzzle? So he developed one that would be understandable, fun, and challenging for anyone at any level. Most importantly, he wanted the puzzle to encourage independent thinking, emphasizing logic, reasoning, concentration, and perseverance. His puzzles immediately met with unbelievable success and are now played the world over by children, adults and the elderly. Since its invention, KenKen has become the world's fastest growing (and most enjoyable) puzzle and has proven to be one of the world's best brain exercises.

Based on the same rules as the hit KenKen(tm) game, as printed in the New York Times and The Times (uk).

Related to Sudoko, but with a mathematical twist - use the arithmetic challenges in each cage to help solve the puzzle.

** Why does this app looks so similar to MathDoku? **
This app is based on the Mathdoku App which was originally created by Ben Buxton and several other contributors. I joined the project of Ben in January 2013. I was the main (and as good as the only) developer for versions 1.96 (released in May 2013) and 2.0 (released in September 2013).
After release of version 2.0 I decided to leave the project of Ben and started development of this app based on a copy of version 2.0.0 of Mathdoku. As a result I am no longer restricted to certain boundaries which were imposed by Ben and I now have full freedom to develop the app the way I want it to be. The users of this app will decide if this was a good decision or not.

Sudoku, KenKen, Hitori, MathDoku, Kakuro, jigsaw and others logic puzzles fans will love Mathdoku+! Simple and challenging, this free brain teaser is unlike anything you’ve played before. Get ready to spend hours of enjoyment along your phone or tablet trying to solve all levels of this classic board game.

With over 700 puzzle levels from 3x3 to the mind blowing 9x9, Mathdoku+ is a great game to help you sharpen logic and math skills whether you’re a beginner or an experienced puzzler!

FEATURES
- Fun and challenging puzzle experience for everyone, from children to adults
- Great for kids’ development of reasoning, logic and math skills

HOW TO PLAY
- The grid size defines the numbers you can use in a puzzle. If it’s a 3x3, you’ll use numbers from 1 to 3. If it’s a 4x4, from 1 to 4. And so on!
- Squares outlined by bold lines are called cages. Each cage has a target number and a an associated math operation.
- Each cage must be filled with numbers that, combined in any order, produce the target number of the cage using the correspondent math operation.
- Numbers may not be repeated in any row or column, just like Sudoku.

Quite simple, eh? So warm up your brain and get ready for Mathdoku+!

Please note! This game is free to play, but it contains items that can be purchased for real money. Some features and extras mentioned in the description may also have to be purchased for real money.

This blissful puzzle application is a colorful, mobile rendition of the popular Calcudoku game -- also known as KenKen or MathDoku. (KenKen is a trademarked name of Nextoy LLC. with which I am not affiliated.)

Calcudoku mixes in arithmetic to the familiar Sudoku-type puzzle game. However, you might find that Calcudoku is often more challenging than the generic Sudoku game. You'll notice that there are various angles that you must exploit to arrive at a unique solution.

I have personally played Calcudoku many times on the online website before I decided to make this app. It's a great game to practice your logic skills and/or relieve your boredom.

Current features:
- Special input controls: You can either drag a cell or use the number pad to add a number.
- Many puzzles: I will keep adding puzzles as long as people keep wanting them. Currently there are 80 puzzles for every size. That's 480 in total.
- Colorful user interface
- Categorized by size: You can choose to play out of any board size between 4x4 and 9x9.
Upcoming features:
- Sounds
- Undo button

MathDoku Extended integrates MathDoku with calculator!

MathDoku Extended is based on the famous work from Ben Buxton and his team. MathDoku is an open source implementation of hit KenKen ® game, as printed in the New York Times and The Times (UK). The game is similar to Sudoku but uses a little math.

MathDoku Extended has several improvements over original Mathdoku:

- integrated call to DigitCalc - a simple calculator that computes all combinations of one-digit numbers which gives a desired result for selected mathematical operation. It is a standalone application which can be used with games such as KenKen ®, MathDoku, Killer Sudoku, Kakuro and similar.

If DigitCalc is called from MathDoku Extended it automatically gives possible combination for selected cage considering already resolved cells and if cage is in line (so without duplicates).

- enable long touch to fill cell. No need to constantly switch between normal and 'maybe' mode. Just tap shortly to put 'maybe' or long touch to put the solution into a cell.

- bigger board
- bigger 'maybe' numbers
- 3x3 digit panel
- new theme with more visible colors

Features removed from original MathDoku:
- swipe
- scrolling text on top
- penalty on check progress
- sharing by e-mail
